Tire tread



FIG. 1 is a perspective view of a tire tread, it being understood that the tread pattern continues uniformly throughout the circumference of the tire tread;

FIG. 2 is a front elevational view thereof;

FIG. 3 is a side elevational view thereof, the opposite side elevational view being identical thereto; and,

FIG. 4 is an enlarged fragmentary front view thereof.

In the drawings, the dark stippled surface shading represents the recessed portion of the tread grooves, having a depth as best shown in FIG. 2; the broken lines defining the tire inner bead and the peripheral boundary between the tire tread and the sidewall are for illustrative purposes only and form no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
